The pressure regulating component of the existing sprayer is provided with an internal thread in the pressure regulating housing, one end of the pressure regulating screw is screwed into the internal thread, and the end of the pressure regulating screw acts on the spring force of the regulating spring to make the spring control the valve The gap between the core and the valve seat is adjusted.
Because the sprayer will vibrate during the working process, a lock nut is screwed on the screw to prevent the screw from loosening due to vibration, resulting in pressure changes and affecting the effect of the sprayer.
The above structure has the following defects: First, because the pressure regulating housing needs to be equipped with springs and other parts, the diameter is larger than the pressure regulating screw, so the upper part is either closed or processed blind holes and then threaded holes, which is more complicated; , Every time you adjust the pressure, you need to loosen the lock nut and then adjust, the operation is more complicated and inconvenient to use.
The purpose of the utility model is to provide a sprayer with convenient pressure regulation and simple structure.
A sprayer includes a sprayer, an elastic sheet is arranged outside the pressure regulating shell of the pressure regulating component of the sprayer, a pressure regulating nut is screwed on the upper end of the pressure regulating shell, and the pressure regulating nut regulates the spring in the pressure regulating shell The spring force of the spring controls the gap between the valve core and the valve seat to adjust the pressure. The pressure regulating nut includes a shell with a blind hole.
The inner end of the blind hole is provided with a threaded part with internal threads arranged coaxially with the blind hole. The outer diameter of the threaded part is smaller than the hole diameter of the blind hole. A number of axial directions are provided on the inner wall of the blind hole. The convex bar is provided, after the pressure regulating nut is screwed to the upper end of the pressure regulating shell, the convex strip acts on the elastic sheet to lock the pressure regulating nut on the pressure regulating shell.
